A — it were warmer.
Reason: the delay is from the time sound takes to travel across the stadium. The speed of sound increases with air temperature (approximately c ≈ 331 + 0.6·T°C), so warmer air makes the sound arrive sooner. Less humidity would slightly lower the speed (so B is wrong), altitude does not raise sound speed (at the same temperature c depends on temperature, not pressure), and shouting louder doesn't change the propagation speed (only the amplitude).
